Power Supply Recommendations

The SN74AVC24T245 device uses two separate configurable power-supply rails, VCCA and VCCB. VCCA accepts any supply voltage from 1.2 V to 3.6 V and VCCB accepts any supply voltage from 1.2 V to 3.6 V. The A port and B port are designed to track VCCA and VCCB, respectively, allowing for low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V and 3.3-V voltage nodes.

The output-enable OE input circuit is designed so that it is supplied by VCCA and when the OE input is high, all outputs are placed in the high-impedance state. To ensure the high-impedance state of the outputs during power up or power down, the OE input pin must be tied to VCCA through a pullup resistor and must not be enabled until VCCA and VCCB are fully ramped and stable. The minimum value of the pullup resistor to VCCA is determined by the current-sinking capability of the driver.
